The new Hopara 2 was inspired by nature. Merino wool is a true miracle fiber: it is breathable and odor-inhibiting, moisture-wicking and temperature-regulating - and ultra-soft to boot! Simply slip into the shoes barefoot and let the 60% merino wool lining pamper your feet. There's also a soft 30% sugar cane insole, speed laces, an adjustable heel strap and CORDURA® mesh overlays to keep water out while protecting your feet from debris on the trail.
